Table $3.$Under a large building, there is a layer of compact sand of unit weight $20$ kN$/$m$3$ extending for a depth of $3$ m below the foundation. Under the sand layer, there is a layer of clay of unit weight $16\mathrm{.}50$ kN$/$m$3,1$ m thick, and beneath clay, there is more sand. The water table is atthe foundation level. The results in Table $3$ were obtained from a consolidation test on a sample of the clay If the mean value of the additional pressure on the clay from the weight of the building is $150$ kN$/$m$2,$estimate the probable final settlement due to the consolidation of the clay.
